HedgeyGedgey Posted January 1, 2020 Share Posted January 1, 2020 As title really, anyone ran some aftermarket cams with a td04 hybrid? Was thinking of getting some of the Fiske Automotive cams Quote Link to post Share on other sites
RobSR Posted January 1, 2020 Share Posted January 1, 2020 It really depends what you want to do with the engine powerband. The nice thing about a TD04 is, it’s relatively responsive, however torque nosedives after ~5200rpm, so you could go for a slightly longer duration cam to help past this point. You will however lose a little bottom end however. If you want to improve the mid range, go for a shorter duration cam with less overlap to help drive the turbo. On a ported head, with stock valves I’ve made power to 8500rpm on a mild lift 272 that you can still use with the stock shim on top of bucket arrangement. It’s quite a nice all rounder. I personally wouldn’t bother with a longer duration unless it’s a drag car and you’re trying to change you EMAP v MAP ratio drastically. Quote Link to post Share on other sites
HedgeyGedgey Posted January 2, 2020 Author Share Posted January 2, 2020 Thanks Rob. Issue I have is when td04 blows, I'll put on a gtx2860r or gt3071. So I'm sort of trying to over spec the entire build bar the turbo, so it will only be a quick swap of turbo and retune Quote Link to post Share on other sites
RobSR Posted January 3, 2020 Share Posted January 3, 2020 272 is just about ok on a 2860 imo, I personally would never go 3071 on a starlet, but if you do and it’s being used on the road,you want to go shorter duration, 25* region or even less unless it’s a drag engine.

Still split decided atm lol Yes we do, we only list a 272 ‘over shim’ online, however we offer various durations, with varying lift. We run a slightly different cam in our new development engine that you have to use a solid bucket/under shim with. Let us know and we can help spec something most suited to your setup Quote Link to post Share on other sites
